CIRCUIT-CONTROLLING TELEPHONE-RECEIVER SUPPORT.

Specification of Letters Patent.

Patented Dec. 10, 191.8.

Application filed November 7, 1914, Serial No. 870,795. Renewed April 24, 1918. Serial No. 230,607.

To all whom it may concern:

Be it known that I, \VILLIAM PICK, a subject of the Emperor of Austria and Apostolic. King of Hungary, residing at Scranton, in the county of Lackawanna and State of Pennsylvania, have. invented certain new and useful Improvements in Circuit-Controlling Telephone-Receiver Supports; and I do herebydeclare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use. the same.

' vMy invention relates to an extension support for telephone receivers, of such character that normally, or when the support is in the collapsed. position, the main line or talking circuit, is broken, but when the support. is extended, the last named circuit is closed. This extension support is of such character that itmaintains the receiver in the proper elevated position for use without the aid of the hand of the user, thus giving the latter the use of both hands during a telephone conversation.

As illustrated in the drawing, the extension support of the lazy tongs type, but it must be ui'idcrstood that. other forms of support which are adapted to be alternately extended and collapsed, may be employed without departing from the spirit. of the invention.

One object of my invention is to provide a receiver. support which shall obviate the requirement that the user of the telephone shall remove the receiver from the hook preparatory to beginning a conversation,

and restore the receiver to the hook after the, conversation is completed. Still another ob-- ject as heretofore intimated, is to obviate the requirement that the user shall hold the receiver in his hand during the conversation. c I

These advantages, which are incident to my improved construction, will greatly facilitate the ease and rapidity of telephonic communication, as will be readily understood, and the invention is therefore believed to be important both to the telephone company and to the subscribers.

Having briefly outlined my improved construction, I will proceed to describe the same in detail, reference being made to the accompanying drawing, in which is illustrated an embodimo-m thereof. ln this drawing,

Figure 1 is a side elevation of a telephone equipped with my improvement.

Fig. '2 is a section taken through the standard and also cutting the. tubular extension carrying the circuit make-aiul-break device of my imprm'ement. This is a front view with the transmitter shown .in elevation, the section being taken on the line 22. Fig. 1. I

Fig. 3 is a similar view with the estersion support shown in place upon the lubu-v lar extension. This may he considered a view looking in the dire tion o'tiarrow 2, Fig. 1.

Fig. 4 is a top plan view of the telephone equipped with in)- improvement. or a view looking in the direction of arrow 4. Fig. l.

the construction being shown partly in horizontal section taken on the line .5, Fig. -3.

Fig. 5 is a similar view, with the cxtcir sion support mostly broken'away, but showing the make-and-brcak device in position for'closing the talking or line circuit.

.The same reference characters indicate the same parts in all the views. 4

Let the numeral 5 designate the standard of the telephone upon which the t. ansinittor 6 is mounted in the usual manner. this standard having the conventional base 7 broken only by an opening 8 covered by a transparent device and through which an indicating or signal light 9 maybe viewed,

the use of which will bc hereinafter more fully explained.

ithin the standard which hollow for the purpose, are located three spring contacts respectively designated by the numerals 10, 11 and 12. ,Thcse contacts are mounted upon an upright metallic plate 13 and are insulated therefrom and from each other by insulated layers. respectively dcsig- (ill nated 1%,,15 and 16. From the contact 10.,

a conductor :17 leads to the signal amp 9 from which 'a second conductor 18 leads 'to the central station, or source of current supply, this conductor being one 'meniberof the" line or talking circuit... ..,F-rom, the central station, the other member 19 of the'lme circuit leads to, a point 2Qfrom ,which one conductor21 leads to the transmitter(awhile another conductor 22 leads from the same,

po'i'nt 20 to the receiver From the transmitter, a conductor 24' leads to the spring I 7 contact 12, which contact, when in its nor-- mal position, or when the telephone is not in use for conversation purposes, is electrially connected with the metallic plate or contact'support .13, through the medium of .a metallic spacing block 25*, which is mounted on the said rod, whereby the ringing circuit is normally completed through the said plate, a screw 26 at the bottom of the base,

a conductor 27.a signal bell and a conductor29, to the ground, asshowir; at. 30; From the contact 11, a conductor 31- leads to the receiver,.the coiitluetor22 being the.

companion conductor, and connected with the receiver, as heretofore explained. two conductors and 31 leave the hollow standard through anzopening 32;'-whence t1hey pass into a laterally disposed tubular member 33, and out through anopening 2L formed in said member. extremity of the hollow standard is formed an exteriorly projecting interiorliy threaded 35 collar -35, forming a socket into whlc-h is the screw entering. the insulating material 38 and so ad usted that the plunger mayibe moved back and forth upon its insulating support .with freedom. Upon 'tlnsplunger is mounted and made fast a stop collar 41 which'engages. one extremity of a spiral spring 4:2 which"surrounds the[-. inner port'ion -13 of the plunger,'thepmbosite eX-' tremity .of the spring engaging the" insulat v ingwasher (it; which rests-against the wall of i the standardaround an opening 44, through which the part 43 of the plunger passes; the inner extremity of the plunger being normally located within the upper'portion of the hollow standard 5 and registers gwith the perforation 45 formed in the rod or upright member 13. The spring-42 normally holds the plunger in the positionshown in 1 Fig. 3, or outfot' engagement with the spring contact '12, the upper'portion of the latter,

Upon the upperhowever being. position tobe acted upon b th plunger? whjenthe lat-t is" forced through theperforation 4.5, "hereinafter explained.

The opposite or ou'ter'extremity of the plunger is ie as shown at 16, whereby gage'the inner conical por- H insulating plug 48-, which is movable in an opening 49 formed iriorie side of thed'evice 331-, [Ehe bodytportion. of this plug is cylindrical. Beyond the cone-shaped 7-5 part 4:7 and" leading from the smaller ex tre'm'ity thereof, is a threaded part or screw 50, which 'enters the: inner end ofa bracket 51, the inner extremity of this bracket being slidable in an opening :52 formed in the de.-. vice 33, directly opposite-,tlie.opening it). Connected with the outer;extremityfofithe; 1 bracket 51 asgshown ;at.53,..i's-.-a la-z'y tongsm structure 51,to thcout-er extremity; of which 3 is secured a bracket 55to which is'made-fast so 1 the receiver 23 by. means of a screw 57 which passes through a lug 58 of the bracket and spaced'ears 49 of the receiver, the connected parts ha ving registering perforations and the screw being fastened by a nut 59. r

t as this lazy tongs member is of the usual constructioin; it is. unnecessary to; describe the same with :ptlrticgl-tltli'ityi'01i111: detail-ins; it will bereadilyunderstoodithat the'joints designated by the numeral 60 are all-pivotal, thus making'it practicable to extend and collapse the receiver support at will, or throw} the same from the dotted line position in Fig. 1, to the full line position in the same figure, or vice versa, as may be required.

To facilitate the support of the-conductors 22 and 31, between the telephone stai'idard. and the-receiven th lazy tongs structure is provided with eyes 61 through which-the Y conductors pass. i-

From the foregoingdescription, theuse and operation of my improvement willbe readily understood. Assuming that the support is in the collapsed position as shown in full lines inF-igg s ti and 1 and in dotted lines in Fig. 1, it will'be understood that the line or. talking circuit is broken, as this circult must be completedth-rough the conductor 17, which leads to the spring contact 10, and the last named contactis insulated in such a manner as to break the circuit, as. best illustrated. inFigm- Now, if it is desired to holda conversation, the user will grasp the receiver, and move the same toward him, until the support therefor, being ,mainly the lazy tongs member 54, is extend-- ed to the position shown in full lines in Fig.

1. During such extension, the lazy tongs member 5 1 is not only extended, but the plug 48 and the bracket 51 are moved in'the tubular'device 33, in the direction of the travel'pf the receiver. This movement is sufficient to cause the coneshaped frustum part 47 of the plug to act upon the beveled 10, as best illustrated in Fig. 2 of the draw-. v

. ta'lkin scribe the ringing circuit is broken, as this extremity 46 of the lunger- 36, and will force the plunger agalnst'the' action of its spring 42, intoengagement :with thecontact 12, whereby the latter is disengaged from the spacing member and brought into engagement with thecompanion contact ing In this event, the talking .or line circuit will be completed and the ringing circuit broken. For instance, the line or talking circuit may be tracedthrough the conductor 19, to the point 20, thence. through the conductor 22 to the receiver, and thence from the receiver through the conductor 31,

the spring contact 11, the spring contact 12,

and the conductor 24, to the transmitter 6,-

and thence. from the transmitter throughthe conductor 21- and the conductor 19? At the same time, the circuit is completed throughthe signal lamp 9, through the medium of the spring contact 10, the conductor 17,

which is connected withthe lamp, and themam line conductor 18. Again, when the circuit is closed .as heretoforejdecircuit can-only be completed through the medium of the spring contact 12 when in engagement with the contact block 25, as heretofore' explained;

When the receiver is in the extendpd position, as just explained, it is supported by the lazy tongs structure in such a manner that .the user may'place his ear thereto and hear the message-without the necessity of using the hand for supporting the receiver, thus leaving both hands free for other use. Now, when the conversation is completed, the receiver maybe moved toward. the telephone standard, whereby the lazy tongs member is thrown into the collapsed position, and

the bracket 51 and plu 48 actuated to return them-to their norma position,thus leav-,

ing the plunger 36 free to return to its normal position, due to the influence of itsspring 42, whereby thetalking or line circuit is broken and the ringing circuit completed. At the same time, .the broken through the signal light which serves to assure the user of the telephone that the talking or line circuit is closed or" broken, as the case may be.

The support for the receiver may be reversible, that is to say, changed from one cgrcuit is sired position of adjustment. By reason of this construction, it becomes practicable to place. the receiver. in position tobe heard through either ear of the user. It sometimes happens that people are deaf in one ear and if it should be the left ear, the ordinary arrangement of the receiver for hearing through the left ear would not be satisfactory. Such persons may therefore reverse the position of the receiver, or throw it to the opposite: side of the instrument from whereit is usually located. The receiver will then be in the proper position to transmitter support, a receiver, an extensible support for said receiver mounted on said hollow support and means for forcing said contact springs into contact mounted in said hollow support and operated by said extensible support.
